By definition, we have to:
In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.
This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.
We have then, that the commutative property of the addition is:
3 + (-7) = (-7) + 3
Answer:
An expression that illustrates the commutative property of addition is:
3 + (-7) = (-7) + 3
Answer:
k = 4
Step-by-step explanation:
-9 +8k = 7+4k
Subtract 4k from each side
-9 + 4k = 7
Add 9 to each side
4k = 16
Divide by 4
k = 4
Plug in the value you got for k:
-9 + 8(4) ? 7 + 4(4)
-9 + 32 ? 7 + 16
23 ? 23
23 = 23
solution
Mean of two smallest number (3+5 =8/2) =4
Mean of all the three (3+5+19 =27) 27/3 = 9
so the mean of two largest number is 19+5 = 24 /2 = 12
Final Answer
The mean of two largest Number is 12
